Original G12M-25 Tone12", 30oz ceramic magnet, 25 watt, 1-3/4" voice coil.British Kurt-Mueller aged and treated ribbed cone. Similar to the original G12M-25, it is aggressive, yet has a smoother overdrive distortion characteristic. Maintains good detail and midrange complexity. More headroom and less compressed than the AlNiCo 1225. Also available with Weber's Hemp cone, which is a smoother, darker tone, with less attack (great for taming treble).
